Two-body relaxation times in heated nucleiNuclear TheoryM.O. KavatsyukO.M. GorbachenkoV.A. PlujkoarXiv
Semi-analytical calculations for the two-body relaxation in softened potentials are presented and compared with N-body simulations. With respect to a Keplerian potential the increase of the relaxation time in the modified potentials is generally less than one order of magnitude, typically between 2 ...
Due to the small relative velocities of the nearby stars in co-planar Keplerian orbits around the SMBH, two-body relaxation is effective enough to affect the evolution of the disk on timescales comparable to its estimated age. In the inner, densest part of the disk, the profile becomes ...
We propose a Uzawa block relaxation domain decomposition method for a two-body frictionless contact problem. We introduce auxiliary variables to separate subdomains representing linear elastic bodies. Applying a Uzawa block relaxation algorithm to the corresponding augmented Lagrangian functional yields a doma...

spin-lattice relaxation timeEPRthree-spin processA semiclassical treatment of electrons coupled to classical molecular dynamics of ions is presented. We consider real time dynamics for electrons at a Vlasov-LDA level and include dynamical correlations by an hling-Uhlenbeck collision term (VUU). ...
The most direct approach for characterizing the quantum dynamics of a strongly interacting system is to measure the time evolution of its full many-body state. Despite the conceptual simplicity of this approach, it quickly becomes intractable as the system size grows. An alternate approach is to ...
